Let's see:
Cutting: You have to cut off the the lower plastic skirt of the bumper and 2 brackets off the face of the cross beam. I cut the plastic with a dremel tool and the brackets with an angle grinder. Because the bumper wraps around everything, the cuts were pretty low stress.
Quality: Seems top notch. Welds look good and the powder coating is excellent. Install was pretty straightforward and everything seems laid out well to get to the bolts etc. for the most part so far. There's some trim work I need to figure out near the door opening on top, the aluminum tread plate seems a little short. Getting the bolts that hold the bumper on the bracket was a pain with my XXL size hands, but my kids helped out and that made things easier. Instructions were adequate for the most part.
Why did I pick this one? Couple of criteria I was looking for.. 1) I wanted to keep the factory trailer hitch, 2) my GX barely fits in my garage length wise, so a permanent tire carrier on the bumper was going to be a no go, 3) and of course price and style were a consideration. I couldn't find many basic rear bumpers on 14+ Gx's that looked good . Expedition One had a holiday special last year + being able to pick up locally swayed me to buy one.
I took some pics of the install and I still need to do some wiring on the lights and finish a few things up. I'll do a complete report in a week or 2 when I sort out the last odds and ends.
